IMPROVEMENT IN LEAD-PENCILS.v

Specification forming part of Letters Patent No. 154,675, datedSeptember 1, 1874; application led October 26, 1871.

CASE B.

To all whom it may concern:

Beit known that I, PHILIP HUFELAND, of the city, county, and State ofNew York, have invented cert-ain new and useful Improvements inLead-Pencils, of which the following is a specification:

In the accompanying drawings, Figures 1 and l* represent verticalsectional views of lead-pencils with rubber erasers inclosed in a papercase or` tube. Fig. 2 is a similar view of the same with a rubber eraserinclosed in a wooden case or tube.

Similar letters indicate corresponding parts.

This invention consists of a lead-pencil having a case or tube, made ofpaper or other material soft enough to be cut with a knife, applied toits end so as to have its exterior surface flush with the exterior ofthe pencilbody, and colored or finished to correspond with the body ofthe pencil, as hereinafter more fully set forth.

In the drawings, the letter A designates a lead-pencil. To one end ofthis pencilI attach a case or tube, B, made of paper or other materialsoft enough to be cut with a knife, and said case or tube being of aform corresponding to that of the pencil, and combined and united withthe pencil so as to have its exterior surface and contour continuous,uniform, and flush with the exterior surface and con- '.lhe en d of thepencil for a short distance is reduced to form a tenon, b, intended toitin the open end of the tubular case or tube B, which said case or tubecontains a rubber eraser, O. The outside diameter of the case or tube Bis equal to the diameter of the pencil, so that when it is applied tothe tenon b, it forms a continuation ofthe pencil, leaving the surfaceof the whole unbroken from end to end, whereby a rubbercontaining caseor tube and an veraser of increased diameter are secured and combinedwith the pencil without disturbing the uniformity of the surface of thepencil; and, furthermore, the operation of combining the rubber eraserwith the lead-pencil, and forming the union of parts, is effected withcomparative ease and facility. The case or tube B may be made of paper,as shown in Fig. 1,

or it may be made of wood, as shown in Fig.

2; but in all cases I prefer such material which allows of being readilycut`with a knife. wood be used the case or tube must necessarily be madeof considerable thickness to prevent it from splitting, and thus thespace for the rubber becomes limited; but if I use paper, leather, orother tough material which can be cut with a knife, I can make the caseor tube quite thin without rendering it liable to split or crack.

By securing the rubber upon the end of the pencil by means of the caseor tube B, the manufacture of the article `is rendered quite easy, andwhen finished the rubber-containin g case or tube and pencil show acontinuous, uniform, and flush surface, and the same, when colored orfinished to correspond with the body of the pencil, presents a neat andattractive appearance.

lt will be understood that the case or tube protects and alfords lateralsupport for the rubber eraser, the end of which eraser projects from thecase or tube a suiicient distance to be used as an eraser. As the rubberwears oli' by usage the tube can be easily cut down, so as to keep theend of the lheraser always exposed, and I am enabled to use the eraserdown to its inner end.

I do not claim, broadly, the combination of a paper case or tube, aneraser, and a leadpencil, as such is the subject-matter of a separateapplication; but

. Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

A lead-pencil having a paper case or tube applied to its end so asto.have its exterior surface flush with the exterior of the pencilbody,and colored or finished to correspond with the body of the pencilfwiththe eraser applied as set forth, the whole constituting a new article ofmanufacture'.

This specification signed this 17th day of October, 1871.
